CASH-REGISTERING MACHINE.

SPECIFICATION forming part of Letters Patent No. 502,645, dated August1, 1893.

A li ati n fil d February 14, 1893. Serial No. 462,308. (No model.)

To all whom il /WNW] concern.-

Be it known that I, JEROME J. WEBsTER, a citizen of the United States,residing at Northampton, inthe county of Hampshire and State ofMassachusetts, have invented new and useful Improvements inCash-Registering Ma chines, of which the following is a specification.

This invention, for improvements in cash registering machines, relatesto the drawer confining and releasing mechanism of the class whichpermits and insures the release of the drawer-catch only after thekey-lever has completed its working movement and is returning to itsnormal position.

The object of this invention is to improve and simplify devices of thisclass; and to this end the invention consists in the construction andcombination of parts all as will hereinafter fully appear and be setforth in the claims.

The improved mechanism is illustrated in the accompanying drawings, inwhich- Figure lisasectional elevation of sufficient portions of a cashregistering machine to clearly show the application thereupon of thetherein included improved drawer-catch-de vice. Figs. 2 and 3 aresectional elevations, as seen at the rear of the plane indicated by theline a:-x, Fig. 1, showing the parts of the draWer-catch-device indifferent relative positions, and to which reference will be hereinaftermade. Fig. 4 is a bottom plan view of the catch device, while Fig.5 is aperspective view of the same.

In the drawings, A represents one of the series of key-levers pivotallysupported in suitable framing above the base or table, B, of themachine, below which the cash-drawer, D, moves in suitable slide-waystherefor.

0 represents the rocker-plate which is tilted as each key-lever ismoved, and which secures, through the link, a, the swinging of the arm,b, on the rock-bar, d, all as usual in a well known type of cashregistering machines.

Below the base, B, is secured a plate or casting, G, having theaperture, f, therethrough while the base, B, is also correspondinglyapertured, as seen at g.

ing a rear part or fixture of the drawer, the spring, 7', causingnormally the maintenance of the catch-lever in its drawer-engagingposition.

The bar, F, is understood as hung upon the arm, b,to move endwise as thearm is swung, and to also have a movement angularly to its endwise play.The lower portion of this bar lies alongside of the forward arm of thedrawer-catch-lever, and is shouldered or step formed as indicated at m,while thereabove the bar has the upwardly and laterally inclinedcam-surface, n. The spring, 0 is applied to force the bar in onedirection transversely of its endwise play.

The operation of this improved mechanism will be now explained: Beforethe key is depressed the bar, F, has its side portion, k, next above thestep, m, alongside the catch-lever, h, as indicated in Fig. 3; as anyone of the keys is depressed the bar, F, is moved upwardly so far thatit may be forced by its spring sidewise to have the shoulder come torest above the catch-lever, see Figs. 1, 2, and 4:. Thus far noreleasing movement of. the catch lever has been effected,but as the keyis in its return movement the bar downwardly returning to its normalposition forces the forward end of the drawer-catchlever down, and therear end of such lever consequently swinging upwardly releases thedrawer to open. It will be furthermore perceived (see Fig. 3) that asthe bar, F, moves downwardly, its cam surface, it, impinging against theborder of the aperture in the plate will so force the bar transversely,against its spring, 0, as to throw the stepped portion, m, off fromengagement with the drawer-catchlever, when the latter will resume itsnormal position to lock the drawer on its next closing.

Care is taken in the construction of the bar that the sidewise throw ofthe cam incline, n, shall exceed the width of overlap which theshoulder, m, may have upon the upper side of the drawer-catch-lever.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. In a cash registering machine, the combination with a drawer, of apivotally mounted catch-lever therefor, a bar movable endwise andactuated by any of the keys of the machine, and also having atransversal play, and having an abutment portion which, as the key isgiven its working movement, is brought to assume a position ofengagement with the catch-lever, and which, movingin conjunction withthe return of the key, causes the releasing swing of the catch-lever,substantially as described.

2. In a cash registering machine, the combination with a drawer, of apivotally mounted catch-lever therefor, a bar movable endwise andactuated by any of the keys of the machine, and also having atransversal play, and having an abutment portion which, as the key isgiven its working movement, is brought to assume a position ofengagement with the catch-lever, and which, moving in conjunction withthe return of the key, causes the releasing swing of the catch-lever andmeans for forcing the bar from engagement with the catch-lever after thelatter has been given its releasing swing, substantially as described.

3. In a cash registering machine, the combination with a drawer, of apivotally mounted catch-lever therefor, an endwise movable bar actuatedby any ofthe key-levers of the machine and having the step-formed lowerend portion and the cam thereabove, the spring which forces the barin adirection angular-1y to its endwise play, and a part against which thecam may impinge, all substantially as described for the purpose setforth.

4. In a cash registering machine, the combination with the rock-shaft,movable in conjunction with the key-levers having the arm, Z), and thedrawer, of the plate, G, supported above the drawer with the aperture,the drawer-catch-lever, h, pivoted at the under side of the plate,thebar hung to said rock-shaft-arm, to move endwise and also free to playtransversely through said aperture, and having the cam surface, 91, andthe step-formed-extremity, m, and the spring, 0, for the bar, and thespring, j, for the catch-lever, substantially as 45 described.
